Description
본 고안은 연료계의 정전기 발생을 감소시킨 연료펌프의 작동속도 제어장치에 관한 것이다.The present invention relates to an operating speed control apparatus of a fuel pump which reduces the generation of static electricity in the fuel system.
연료시스템에 있어서 연료펌프로부터 급송되는 연료를 안내하는 연료파이프를 비롯한 연료계의 재질로는 차량의 무게를 경감하기 위해 플라스틱 재질이 통상 사용되고 있다.In the fuel system, a plastic material is commonly used as a material of a fuel system including a fuel pipe for guiding fuel supplied from a fuel pump to reduce the weight of a vehicle.
이와같이 플라스틱 재질은 강도는 크고 무게가 가볍기 때문에 연료계의 재질로 많이 사용되고 있으나 정전기가 많이 발생하는 문제점 및 특히 연료펌프에서 정전기 발생이 많이 생기게 되는 바 정전기는 연료의 유동속도가 빠를수록 많이 발생하는 특성이 있다. 그러나 종래의 경우 엔진이 필요로하는 연료량에 상관없이 연료펌프는 일정량의 연료를 보내고 여분의 오일은 압력조절기를 통해 리턴시키게 되므로 엔진의 저속구동시 연료펌프가 불필요하게 많은 연료를 이송시켜 정전기 발생을 증가시키게 되는 문제점이 있었다.As such, plastic material is widely used as a fuel material because of its high strength and light weight, but there are many problems in generating static electricity, and especially in the fuel pump, which causes more static electricity. There is this. However, in the conventional case, the fuel pump sends a certain amount of fuel regardless of the amount of fuel required by the engine, and the excess oil is returned through the pressure regulator. Therefore, the fuel pump transfers a large amount of fuel unnecessarily during low-speed operation of the engine to prevent static electricity. There was a problem that was increased.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 플라스틱 재질을 사용하는 연료계에서 엔진의 저속구동시 연료펌프의 속도를 낮추어 연료유동 속도를 줄이므로써 정전기 발생을 감소시킨 연료펌프의 작동속도 제어장치를 제공하는 데 있다.The present invention has been proposed in view of the above problems, and its purpose is to reduce the generation of static electricity by reducing the fuel flow rate by lowering the speed of the fuel pump during low-speed operation of the engine in a fuel system using plastic materials. It is to provide a fuel pump operating speed control device.
본 고안은 상기한 목적을 달성하기 위하여 연료탱크로부터 연료를 퍼올려 급송하는 연료펌프를 비롯한 플라스틱 재질을 주재료로 하는 연료계에 있어서, 흡기매니폴드내의 온도를 검출하여 이를 전기적 신호로 출력하는 흡기온도 감지센서와;배기매니폴드내의 온도를 검출하여 이를 전기적 신호로 출력하는 배기온도 감지센서와; 상기 흡기온도감지센서와 배기온도감지센서로부터 검출된 온도차의 변화를 체크하여 온도차에 비례하여 상기 연료펌프의 구동속도를 제어하는 전자제어장치와; 를 포함하여 구성된 것을 특징으로 한다.The present invention is a fuel system mainly made of a plastic material, including a fuel pump for pumping up the fuel from the fuel tank to achieve the above object, the intake temperature for detecting the temperature in the intake manifold and outputting it as an electrical signal An exhaust temperature sensor for detecting a temperature in the exhaust manifold and outputting it as an electrical signal; An electronic controller which checks a change in temperature difference detected by the intake temperature sensor and the exhaust temperature sensor and controls the driving speed of the fuel pump in proportion to the temperature difference; Characterized in that configured to include.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 연료계의 연료펌프의 작동속도 제어장치를 나타내는 도면으로 도면중 부호 1은 연료탱크(2)내의 연료를 퍼올려 연료파이프(3)를 통해 엔진(4)에 급송하는 연료펌프이다.1 is a view showing the operating speed control device of the fuel pump of the fuel system according to the present invention, the reference numeral 1 in the drawing is to pump the fuel in the fuel tank (2) to feed the engine (4) through the fuel pipe (3) It is a fuel pump.
상기 연료파이프(3) 및 연료펌프(1)를 비롯한 연료계의 대부분의 재질은 차량무게의 경감을 위하여 플라스틱재로 형성된다.Most of the materials of the fuel system, including the fuel pipe 3 and the fuel pump 1, are formed of a plastic material to reduce the weight of the vehicle.
상기 엔진(4)에 공기를 도입하는 흡기매니폴드(5)에는 흡기온도감지센서(6)가 설치되며 상기 흡기온도 감지센서(6)는 흡기의 온도를 검출하여 이를 전기적 신호로 출력한다. 그리고 배기매니폴드(7)에는 배기가스의 온도를 검출하기 위한 배기온도감지센서(8)가 설치되어 있으며 검출된 배기가스의 온도는 전기적 신호로 출력되어 후술하는 전자제어장치(9)에 인가된다.An intake air temperature sensor 6 is installed in the intake manifold 5 that introduces air into the engine 4, and the intake air temperature sensor 6 detects the temperature of the intake air and outputs it as an electrical signal. The exhaust manifold 7 is provided with an exhaust temperature sensor 8 for detecting the temperature of the exhaust gas, and the detected exhaust gas temperature is output as an electrical signal and applied to an electronic controller 9 described later. .
전자제어장치(9)는 흡기온도 감지센서(6)와 배기온도 감지센서(8)로부터 인가받은 신호에 의해 양자의 차, 즉 온도차를 계산하여 그 온도차에 비례하여 연료펌프(1)의 구동속도를 제어한다. 즉, 엔진의 속도가 빨라지면 연료소모량이 많아지며 흡기매니폴드와 배기매니폴드의 온도차(절대값)가 커지게 되므로 이때는 연료펌프(1)의 구동속도가 높게 유지되도록 제어하게 되며 엔진의 속도가 느려지면 연료소모량이 낮아지고 흡배기 온도차는 낮아지게 되므로 이때는 연료펌프의 구동속도를 느리게 제어하는 것이다. 이에따라 엔진의 저속구동시 연료펌프로부터 불필요하게 많은 연료의 이송이 방지된다.The electronic controller 9 calculates the difference between the two, i.e., the temperature difference, based on the signals applied from the intake temperature sensor 6 and the exhaust temperature sensor 8, and proportionally drives the driving speed of the fuel pump 1 in proportion to the temperature difference. To control. That is, as the engine speed increases, fuel consumption increases, and the temperature difference (absolute value) between the intake manifold and the exhaust manifold increases, so that the driving speed of the fuel pump 1 is controlled to be maintained at a high speed. If it is slow, the fuel consumption is lowered and the intake / exhaust temperature difference is lowered. At this time, the driving speed of the fuel pump is controlled slowly. This prevents unnecessary fuel transfer from the fuel pump at low speeds of the engine.
이상과 같은 본 고안의 연료펌프의 작동속도 제어장치에 의하면 연료펌프의 구동속도를 흡배기 온도차에 비례하여 제어하게 되므로써 저속운전시 불필요하게 많은량이 연료펌프로부터 펌핑되는 것을 방지하여 연료의 유동속도를 낮춰 연료시스템의 정전기 발생을 줄이게 되는 효과가 있다.According to the operating speed control device of the fuel pump of the present invention as described above, by controlling the driving speed of the fuel pump in proportion to the intake and exhaust temperature difference, it is possible to reduce the flow rate of fuel by preventing a large amount of pumping from the fuel pump unnecessarily during low speed operation. The effect is to reduce the generation of static electricity in the fuel system.
